Employees FAQ 3

Does vacation or sick leave count
towards the number of hours worked in a week when calculating whether
an employee is entitled to overtime (or compensatory time if used)?

No. The Fair Labor Standard Act's (FLSA)
requirement to pay overtime for hours worked in excess of 40 weekly
applies only to actual hours worked. Paid vacation or sick leave is not
considered hours worked under the FLSA. Wisconsin law follows the FLSA.
